Extindere disk live in Ubuntu 2X.04 LTS
Cu VM pornit verificam disk-ul in scop cu ce partitii, VG si LV se prezinta:
# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
......
sdb 8:16 0 10G 0 disk
└─sdb1 8:17 0 10G 0 part
├─vg_wiki-lv_wiki_1 252:1 0 6G 0 lvm /wiki/lv1
└─vg_wiki-lv_wiki_2 252:2 0 4G 0 lvm /wiki/lv2
......
Extindere HDD
Procedam la extinderea disk-ului in hypervisor (ex Proxmox VM):
Fara a restarta masina virtuala este nevoie de rescanarea disk-ului pentru a colecta informatiile legate de noua capacitate:
# echo 1 > /sys/block/sdb/device/rescan
Apoi ne asiguram ca OS-ul scanat disk-ul:
# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
......
sdb 8:16 0 15G 0 disk
└─sdb1 8:17 0 10G 0 part
├─vg_wiki-lv_wiki_1 252:1 0 6G 0 lvm /wiki/lv1
└─vg_wiki-lv_wiki_2 252:2 0 4G 0 lvm /wiki/lv2
......
Extindere Partitie
Dupe ce a fost extins disk-ul fizic trebuie extinsa si partitia aflata pe respectivul disk:
# growpart /dev/sdb 1
CHANGED: partition=1 start=2048 old: size=20969472 end=20971519 new: size=31455199 end=31457246
# pvresize /dev/sdb1
Physical volume "/dev/sdb1" changed
1 physical volume(s) resized or updated / 0 physical volume(s) not resized
